This follows on from my previous post.
It is an observable fact that our direct experience alone does not provide us with sufficient evidence to say whether or not objects in the world arise solely from consciousness (ie. philosophical idealism), or whether consciousness is a product of the material word (eg. the human brain) which in turn perceives an image of that material world (ie. philosophical realism).
Not that these are the only two possibilities – there other theories that could also account for our present experience, and perhaps other explanations that our limited human minds are incapable of understanding – but for the purposes of this article we will not go into this.
The point is, from our direct experience alone, we do not know if what we call the body is solely an image that arises in our consciousness, or if that image is a representation of a real body somewhere outside our consciousness which in turn gives rise to consciousness.
